Chemical Passivation of Silicon Nanowires with C1-C6 Alkyl Chains through Covalent Si-C Bonds

We report on the functionalization of Si NWs with C1-C6 alkyl chains using a versatile two step chlorination/alkylation process. We show that Si NWs terminated with C1-C6 molecules, through Si-C bonds,...

Two Channel Microfluidic CARS for Quantifying Pure Vibrational Contrast of Model Analytes

We discuss the combination of a CARS-imaging system with microfluidics. Such system is a versatile tool to quantify the relative contributions of resonant and non-resonant scattering at the CARS frequency....

Biomedical imaging by means of linear and non-linear Raman microspectroscopy

Biomedical imaging by means of nonlinear Raman microspectroscopy offers novel approaches towards individualized decisions on therapy routines as diagnosis is possible on the chemical composition of tissue...

Photo-induced processes in new materials for electro-optical applications

We present a spectroscopic study of the photoinduced excited-state processes in new materials for polymer solar cells and organic-light emitting diodes, which are based on extended conjugated terpyridine...

Spectroscopic insights into the function of a supramolecular hydrogen-evolving photocatalyst

Two-channel microfluidic CARS: experimental quantification of pure vibrational contrast in CARS images

The combination of linear and nonlinear Raman microspectroscopy has been established to be a powerful tool for biomedical diagnostics. In this contribution we discuss our recent approaches towards CARS...

Excited-state Dynamics in Ruthenium(II)-Polypyridine-Based Black Absorbers and White Emitters

One platform, multiple insights-Editorial

A number of advanced optical imaging modalities have been invented over the past 20 years. These developments include (1) advanced fluorescence imaging based on two-photon excitation fluorescence (TPEF)...

Nonlinear optical imaging: toward chemical imaging during neurosurgery

Tumor recognition and precise tumor margin detection presents a central challenge during neurosurgery. In this contribution we present our recent all-optical approach to tackle this problem. We introduce...

Multimodal Nonlinear Microscopy: Histopathology of Brain Tumors

Biophotonics provides - amongst others - "all-optical" technology for clinical diagnostics. Here we focus on the description of a novel biophotonic tool to assist in the diagnosis and localization of brain...
